    "abstract": "We show that isospin non-diagonal terms should appear in the mean field\nHamiltonian when neutron-proton symmetry is broken. They give rise to charge\nmixing in the single-particle wave-functions. We study the Time Dependent\nHartree-Fock response of a charge-exchange excitation which generates a charge\nmixing in Ca isotopes. We find an enhancement of the low energy proton emission\nin neutron-rich isotopes interpreted in terms of a charge oscillation below the\nbarrier.",
